Abstract: 662,576. Aerials. SADIR CARPENTIER. June 14, 1949 [June 14, 1948], No. 15864/49. Class 40 (vii). The invention relates to an aerial system comprising two spaced vertical dipoles interconnected in such a manner that the effects of the horizontal connection members are eliminated whereby errors due to horizontal components in the received field are removed. In such a system the corresponding halves (top or bottom halves) of the dipoles are connected together by connections at least one of which is interrupted and the receiver is fed from across the interruption or interruptions. In one system 1, 2 and 3, 4 are the two dipoles and the top elements 2 and 4 are directly connected by conductor 11 and the bottom elements connected through conductors 5 and 13 between which the feeder 7, 8, and receiver 14 are inserted. The aerial system of the invention may be used in the same way as a two-dipole Adcock system for durationfinding by the null method. It is stated to be an improvement over the equivalent Adcock system connection in that strict symmetry in the connecting leads between the two dipoles is not essential: If the leads 5 and the equivalent part of 11, and 13 and the other part of 11, are made such that the time of signal travel along them is different it is said that the null will lie in a plane making an acute angle with that containing the dipoles. If both the horizontal connecting leads are interrupted, coils may be inserted in the interruptions coupled respectively with two secondaries connected in series across the input leads. Specification 130,490, [Class 40 (v)], is referred to.
